Commissioning solar panels – now in four minutes flat.

Commissioning solar panels for a single-family home can take up a good half a day. But it doesn’t have to be that way. Hoval has now reduced this to four minutes, representing considerable time savings. And time, after all, is money.

Every installer has probably muttered a few choice words under their breath when doing this kind of work on a single-family home. The thermal solar collectors are installed, but now it’s time for commissioning – something that could easily take up half a day. Hoval has now reduced this to four minutes thanks to the new SolKit® aqua hot water storage tank and the proven UltraSol® solar collector.

Storage tank, solar collector and casing: A triumphant trio for rapid commissioning

SolKit® aqua, the new hot water storage tank, is equipped with an especially large heat exchanger and a set of solar fittings. The secret behind the rapid rate at which the solar panel can be filled and commissioned lies in its red casing, which helps to deliver a burst of speed. It contains two ready-to-connect hoses and a valve for quickly and easily filling the large-volume heat exchanger with solar fluid from the canister via a self-contained system. And the panel can be commissioned while the solar fluid is flowing into the system – even when the sun is shining. There is no longer any need to climb onto the roof, and something that used to be a problem in a solar circuit has been turned into an advantage: air in the system.

More stable operation thanks to a low stagnation temperature

Following commissioning, practically all of the solar fluid is located in the heat exchanger of the SolKit aqua®. While air can be found in the connecting pipes and the collectors, this doesn’t stop the panel from working safely and reliably. Air is distributed together with the solar fluid in the pipes, as well as in the upper pipe sections of the heat exchanger. The lower pipe sections are completely filled with fluid, ensuring reliable system operation. Any minute amounts of solar fluid residue in the collectors retain their function, as the collector design prevents the maximum temperature being exceeded. What’s more, the low stagnation temperature prevents excess pressure in the system.

Combination options with heat pumps or condensing boilers

The SolKit® aqua LT model is designed to be combined with heat pumps and holds 500 litres. The SolKit® aqua HT version, meanwhile, is ideal for gas or oil condensing boilers. There are two volumetric capacities to choose from in this case: 400 or 500 litres.

SolKit® aqua, UltraSol® and the speedy red casing are a powerful triumvirate, significantly reducing the amount of work required for the installer.
